ANTILOPIN.^ 31 



GoA, Eagoa, or Ata. 



Typical locality Hundes district of Tibet. 



Size relatively small, the shoulder-height being about 

 24 or 25 inches. Horns relatively long and slender, much 

 compressed, and heavily ridged, arising vertically from skull, 

 and then curving evenly and regularly backwards with but 

 little divergence, the tips bending upwards and slightly 

 inwards ; no face-glands, inguinal glands, or knee-tufts ; 

 coat in winter close and thick, in summer short ; general 

 colour in winter pale fawn, darkening posteriorly, and 

 becoming almost rufous near the large white rump-patch, 

 which surrounds the root of the very short tail ; in summer 

 the general colour slaty grey ; ears short, narrow, pointed, 

 and well haired ; under-parts white ; limbs white or very 

 pale fawn. Skull relatively broad, without distinct lachrymal 

 depressions, and with relatively broad nasals, tapering 

 evenly forwards ; basal length about 6 J inches. Grood horns 

 measure from 12 to 14^ inches in length, with a basal girth 

 of from 3^ to 4f , and a tip-to-tip interval of from 2 to 

 3f inches. The range extends from the high ranges of 

 Spiti and the Changchenmo district of Ladak through the 

 Tibetan plateau to Kan-su, Shen-si, and the Tatung-gol 

 Valley, a tributary of the Hoang-ho, to the north of 

 Koko Nor. 



Pousargues regards this species as showing affinity with 

 Fantholops, although in the absence of inguinal glands it is 

 markedly different from that genus. The late appearance of 

 the anterior lower premolar may foreshadow the loss of that 

 tooth in PanthoIojJS.
